What You Need to Gather

Essential Clinical Documentation

HAE Diagnosis Confirmation:

  • ICD-10 Code: D84.1 (Deficiency of C1 esterase inhibitor)
  • Lab Results: C1-INH antigenic level, C1-INH functional assay, serum C4 level
  • Genetic Testing: SERPING1 gene analysis (if available)

Prior Therapy History:

From our advocates: We've seen cases where patients had strong clinical justification but weak documentation of prior therapies. A simple one-page summary from your specialist listing "tried Haegarda 40 units twice weekly from [date] to [date], discontinued due to injection site reactions and continued breakthrough attacks" can make the difference between approval and denial.

FAQ: Your Most Common Questions

How long does BCBS prior authorization take in Washington? Standard prior authorizations typically take 15 business days. Expedited reviews for urgent cases must be completed within 72 hours.

What if Takhzyro isn't on my formulary? You can request a formulary exception by demonstrating medical necessity and lack of suitable alternatives. Include documentation of failed step therapy requirements.

Can I get an expedited appeal if I'm having frequent attacks? Yes. If your health could be seriously jeopardized by delays, both internal appeals and external IRO reviews can be expedited to 72-hour timelines.

Does Washington's external review cost anything? No. External review through an Independent Review Organization is free to consumers and legally binding on insurers.

What happens if I miss an appeal deadline? Contact the Office of the Insurance Commissioner immediately at 1-800-562-6900. They may be able to help depending on circumstances, but acting quickly is essential.

Can I use Takhzyro while my appeal is pending? Check if your plan offers "continuation of benefits" during appeals. Otherwise, explore manufacturer support programs or temporary alternatives with your physician.

Do I need to restart the process if I switch BCBS plans? Generally yes, as each plan has its own formulary and prior authorization requirements. However, your clinical documentation can be reused.

How often do I need to renew authorization? Most BCBS plans require reauthorization every 6-12 months with updated clinical documentation showing continued medical necessity and effectiveness.
